Ordered the coolant surge tank for my 2015 Chevrolet 2500 HD LT
Ordered the coolant surge tank for my 2015 Chevrolet 2500HD LT, install took about 20 min and the fitment was perfect, bolt holes lined up and old hardware mounted it perfectly. Have been running it for about a week and love it, would highly recommend using this surge tank for the price. Only issue is the new coolant level sensor does not connect to the factory harness but with 2 red wire connectors you will be all set.
